Definitions
- the present invention relates to an aluminum alloy welded component provided to manufacture vehicular wheels and housings, which are formed with a coating by anodizing after end portions of (an) aluminum alloy member(s) have been integrally welded by friction stir welding.
- a plate-shaped aluminum alloy member is made into a cylindrical shape, and then end portions thereof are butted against each other and integrally welded by friction stir welding therebetween, to make a cylindrical component.
- both ends are flared to make the product.
- a coating is formed by anodizing the design surface, which is the surface on the opposite side of the welded section.
- a side member and a cover member which are both made from an aluminum alloy material, are integrally welded by friction stir welding.
- the integrally-welded side member and the cover member are face milled to smoothen the outer surface of the welded section side, including the welded section, and then a coating is formed on the design surface by anodizing to improve corrosion and wear resistance properties.
- color tone variations may occur in the coating due to differences of the crystal grain sizes between the portions corresponding to the welded section and other portions.
- the color tone variations which exist between the portion corresponding to the welded section in the coating of the aluminum alloy welded component and the other portions, may not be sufficiently improved.
- the cross-sectional microstructures of the welded section obtained by friction stir welding and the other portions of the aluminum alloy welded component were first compared in detail using an optical microscope.
- second phase particles of 2 ⁇ m or larger were decreased because the second phase particles made of coarse Al-Fe-Si particles were finely pulverized by the stirring, and second phase particles of 5 ⁇ m or larger were scarcely found.
- welded section equivalent portion the portion in the design surface that forms the coating
- Patent Reference 3 relates to a method of producing a complex-shaped aluminum article for use in semiconductor processing apparatus, wherein welding has been employed to form said article, comprising: selecting a high purity aluminum alloy with controlled particulate size and distribution and controlled composition of impurities present in said alloy, and welding said high purity aluminum alloy using frictional welding, wherein a variation in hardness between a weld line and a welded parent material is less than about 15 %.
- Patent Reference 4 relates to a method for joining an aluminum alloy material, wherein an aluminum alloy material of a lid material and a side material that are to be integrally joined is a 5000 series alloy including second phase particles with a particle diameter of ⁇ 5 ⁇ m whose distribution density v is 10000 ⁇ v (pieces/mm 2 ), wherein friction stir welding is carried out to a joint part of the ends under such conditions that a diameter d of a shoulder of a tool is 3 ⁇ d ⁇ 8 (mm) and the number r of rotations of a tool is 0.5 ⁇ r ⁇ 6 (rotation/mm, the number of rotations of the tool per joint length of 1 mm).
- the problem to be solved is that it has not been possible to eliminate color tone variations attributable to the inhomogeneous dispersion of second phase particles at the welded section equivalent portion in the coating formed by anodizing the aluminum alloy welded component.
- an aluminum alloy welded component of the invention is formed by (an) aluminum alloy member(s), which include(s) Mg: 0.3% to 6.0% (mass%, hereinafter the same), Cu: 0.2% or less, Si: 0.1% or less, Fe: 0.1% or less, the balance being Al and inevitable impurities, in which the grain size of second phase particles of Al-Fe-Si dispersed within the aluminum alloy member(s) is 5 ( ⁇ m or less when observed with an optical microscope, mutually-facing end surfaces of the aluminum alloy member (s) are integrally welded by friction stir welding so as to form a welded section, and a coating is formed by anodizing a surface of the welded section, or an opposite surface thereof.
- the amounts of Si and Fe that form second phase particles, and the average diameter of the second phase particles, within the aluminum alloy member(s) are controlled, the inhomogeneous dispersion of the second phase particles is suppressed, even if the aluminum alloy member(s) is (are) welded in the welded section equivalent portion by friction stir welding and even as compared to the other portions.
- variations of pit formation caused by etching between the welded section equivalent portion and the other portions become small, it is possible to prevent color tone variations in the coating of the aluminum alloy welded component.
- Mg contained in the aluminum alloy welded component contributes to adjusting the strength of vehicular wheels and housings. Therefore, because the strength is insufficient with less than 0.3% and shaping becomes difficult with more than 6.0%, while Mg should be 0.3% to 6.0%, for a good balance of ensuring strength and ease of shaping, it is preferably 1.0% to 6.0%, and more preferably 2.0% to 6.0%.
- Cu contributes to homogenizing the color tone of the entire coating after anodizing. Therefore, because the coating after anodizing will be turbid with more than 0.2% due to the effect of fine precipitates of Al-Cu particles, 0.2% or less is included according to the present invention.
- Si and Fe form second phase particles made of Al-Fe-Si; if the amounts of Si and Fe are more than 0.1%, coarse second phase particles of Al-Fe-Si that exceed a grain size of 5 ⁇ m can easily form. Therefore, although the coarse second phase particles are preferably pulverized in the welded section during friction stir welding, the second phase particles, including the coarse particles, are inhomogeneously dispersed in the welded section equivalent portion by the agitation of the friction stir welding. As a result, variations of pit formation caused by the etching increase due to the second phase particles being inhomogeneously dispersed in the welded section equivalent portion as compared to other portions, and color tone variations in the coating are caused. Therefore, according to the present invention, the amounts of Si and Fe are preferably 0.1% or less and more preferably 0.07% or less.
- the second phase particles of Al-Fe-Si within the aluminum alloy member (s) are dispersed in the aluminum alloy welded component of the present invention in an amount of 10000 particles/mm 2 or less when observed using an optical microscope. If the second phase particles of Al-Fe-Si dispersed within the aluminum alloy members are thus reduced, the dispersion of the second phase particles in the welded section equivalent portion caused by the agitation during the friction stir welding can be minimized as compared to the other portions. As a result, variations of pit formation caused by the etching become less, and the color tone variation in the coating can be eliminated more reliably.
- the inhomogeneous dispersion of the second phase particles is a cause of the color tone variation in the coating formed by anodizing the above-described aluminum alloy welded component. Therefore, if the distribution density of the second phase particles when observed using an optical microscope is greater than 10000 particles/mm 2 , the dispersion of the second phase particles in the welded section equivalent portion during friction stir welding becomes more inhomogeneous as compared to the other portions. Therefore, variations of pit formation caused by the etching increasingly cause color tone variations in the coating.
- the presence of second phase particles is reduced to prevent their inhomogeneous dispersion in the welded section equivalent portion, and the distribution density of the second phase particles when observed using an optical microscope is set to 10000 particles/mm 2 or less.
- the aluminum alloy welded component of the present invention even though a coating formed by anodizing is formed on the side of the welded section surface or the surface opposite thereof, by limiting the amounts of metal (s) forming the second phase particles, and the grain sizes of the second phase particles, in the welded section equivalent portion and the other portions, it has the excellent effect that a higher quality aluminum alloy welded component product can be achieved, because a uniform coating is formed that reliably eliminates color tone variations caused by the inhomogeneous dispersion of the second phase particles. Further, by controlling the distribution density of the second phase particles, the elimination of color tone variations can be achieved more preferably.
- the objective i.e. to eliminate color tone variations existing between the welded section equivalent portion and the other portions in the coating of the aluminum alloy welded component welded by friction stir welding, is realized by limiting the amounts of Si and Fe that form second phase particles, and by limiting the grain sizes of the second phase particles. Further, by limiting the distribution density, it is realized in a more preferable manner.
- inventive materials and the 5052 material test materials of the comparative examples were obtained by producing an ingot by semi-continuous casting, homogenizing, forming them to have a thickness of 2.5 mm by hot rolling and cold rolling and then annealing to the O-temper (full-softening material).

- the longitudinal end surfaces of the aluminum alloy members of the inventive materials 1, 2, and 3 serving as examples of the present invention and the 5052 Materials 1 and 2 serving as the comparative examples were integrally welded by friction stir welding on abutted portions to form a welded section; after welding, 0.5 mm of the surface layer of the welded surface, including the welded section, was removed using a milling machine, then a rough surface finish was prepared by shot blasting and an anodized coating having a thickness of 10 ⁇ m was formed by anodizing with sulfuric acid.
- microstructures were observed after removal of 0.5 mm by face milling in the welded section equivalent portion and the other portions of the inventive materials 1, 2, and 3 according to the examples of the invention and the 5052 Materials 1 and 2 of the comparative examples. After buffing and then etching with 5% hydrogen fluoride, the microstructures were magnified 400 times using an optical microscope, and the number of particles per 1 mm 2 was obtained by measuring using an image analysis at 1 ⁇ m dot pitch grain size.
- the second phase particles were homogeneously dispersed in the welded section equivalent portion on the opposite surface as compared to the other portions; in inventive material 1, the largest particle diameter was 5 ⁇ m, and the distribution density of the second phase particles equal to 5 ⁇ m or smaller was 7350 particles/mm 2 ; in inventive material 2, the largest particle diameter was 4 ⁇ m, and the distribution density of the second phase particles equal to 4 ⁇ m or smaller was 2310 particles/mm 2 ; in inventive material 3, the largest particle diameter was 5 ⁇ m, and the distribution density of the second phase particles equal to 5 ⁇ m or smaller was 4150 particles/mm 2 ; in the aluminum alloy welded components for the 5052 Materials according to the comparative examples, the second phase particles were inhomogeneously dispersed in the welded section equivalent portion as compared to the other portions; in 5052 Material 1, the largest particle diameter was 6 ⁇ m, and the distribution density of the second phase particles equal to 6
